BayLibre has continued contribution to the open-source community as seen with this new version of U-Boot v2021.10, released on 4th October 2021.

For those unfamiliar, U-Boot development takes place in release cycles which normally span two months. The merge window for the next release (v2022.01) is open until the first release candidate (-rc1) on October 25th. The release of v2022.01 is expected on 10th January 2022 but that is only an estimate.

Our engineers Mattijs Korpershoek, Guillaume La Roque and Neil Armstrong focused on improving support of the Amlogic SoC family in this release. Notable contributions include:

• Add AVB (Android Verified Boot) support for meson64_android
• Implement A/B slot support using the U-Boot ab_select command for meson64_android
• Enable the standard Android boot flow for the SEI-610 and SEI-510 boards (which are based on Yukawa)
